Detailed explanation-1: -Sunlight is the ultimate energy source. Nutrient cycling is a cyclic process that encompasses the movement of nutrients from the physical environment to living organisms and back to the environment. Nutrients are present on the earth where they are recycled, transformed into different forms and reutilized.
Detailed explanation-2: -The ways in which an element-or compound such as water-moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle. Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.
Detailed explanation-3: -Like water, nutrients pass through organisms and the environment through biogeochemical cycles. nutrients. Every organism needs nutrients to build tissues and carry out life functions. Nutrients pass through organisms and the environment through biogeochemical cycles.
Detailed explanation-4: -The term biogeochemical cycle denotes that the nutrients like carbon, hydrogen, phosphorus, etc. move through the biological systems and the geological systems (abiotic components). Hence, nutrient cycling is called the biogeochemical cycle.
Detailed explanation-5: -In ecosystem, cycling of nutrients is called biogeochemical cycle. In this, essential nutrients moves through biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments in an ecosystem. The various biogeochemical cycle includes carbon cycle, nitrogen cycle, phosphorous cycle, oxygen cycles.
